Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.05080 | $0.05080 |
| Opus 5.5 | $0.02032 | $0.02032 |
| Sonnet 5.5 | $0.01016 | $0.01016 |
| Haiku 4.5 | $0.00508 | $0.00508 |
Grade A, and why
psd-claude-plugins CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 14d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 270 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Repository Overview
This is the PSD Plugin Marketplace — a multi-plugin marketplace for Claude Code and Claude Cowork, maintained by Peninsula School District.
Version: 2.37.1 Status: Production-Ready
Plugins
| Plugin | Purpose | Skills | Agents |
|---|---|---|---|
psd-coding-system |
AI-assisted development workflows | 9 | 44 |
psd-productivity |
Productivity workflows (Cowork-friendly) | 33 | 1 |
n8n |
Opt-in MCP connection to PSD's n8n instance (n8n-instance server). Starts disabled |
0 | 0 |
documenso |
Opt-in MCP connection to PSD's Documenso instance (documenso server). Starts disabled |
0 | 0 |
collab |
Threads between people's Claude Code agents — hooks (pane, status entry, toasts, listening) + the hosted collab MCP server |
0 | 0 |
collab is not developed here. It is published into this marketplace from psd401/psd-collab-mcp (recorded in plugins/collab/.publish-source), which also holds its server and is its own marketplace (psd-collab). Fix it upstream and re-publish; do not hand-edit plugins/collab/.

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
